Here's a look inside of Honda and Acura's V6 J37A4 engine and how it works! The J series engine dates back to the mid 90's and is almost 30 years old. It features a single overhead camshaft, powering a rocker arm system equiped with variable timing electronic control, or VTEC. It powers the camshafts through a timing belt, which also turns the water pump. These regarded as outdated in this time as it often requires an expensive preventative service every 7 years. The engine in this video was from a 2012 Acura TL with more than 200,000 km on it. It had low compression in one cylinder. Upon teardown, the exhaust valve on one cylinder was burnt out and had a piece missing, causing the low compression. While the engine could have been saved with a head job and valve replacement, upon further teardown, the engine was burning oil (evidenced by alot of carbon built up on the piston), but it was also ran low on oil a few times as the connecting rod bearings shows severe wear, and even one bearing was worn. Oil burning and carbon buildup is quite common on these J37's. Its a result of using incorrect fuel, driving the car hard when cold and driving around with a misfire. These generation of vehicles have aged and become quite cheap on the market, lending 300HP+ to those who often can't maintain and neglect them. The design of these engines are quite old school and some versions (like the J35 without VCM) have proven to be reliable, using all metal components for cooling, intake, valve covers and oil pans. While dated, this engine's future is uncertain as emission laws tighten and larger engines become a thing of the past as we eventually transition to alternate powered transport, be it hybrids, steam powered or hydrogen powered transportation pods.
